Draft61850-7-1©1EC:2002 -8-57WG10-12(61850-7-1)R2-02/Draft FD1S INTRODUCTION This part of IEC 61850 gives an overview on the architecture of the co-operation and commu- nication between substation devices like protection devices,breakers,transformers,substa- tion hosts etc. This document is part of a set of specifications which details a layered substation communi- cation architecture.This architecture has been chosen to provide abstract definitions of classes (representing hierarchical information models)and services such that the specifica- tions are independent of specific protocol stacks,implementations,and operating systems. One of the essential objectives of IEC 61850 is the specification of provisions to support open interoperable functions and information exchange for various applications in the substation domain.Interoperable functions may be those functions that represent interfaces to the proc- ess (e.g..circuit breaker)or substation automation functions such as protection functions This part of IEC 61850 uses simple examples of functions to describe the concepts and meth- ods applied in IEC 61850. This part of IEC 61850 illustrates the relations between other parts of IEC 61850,e.g.,part IEC 61850-6,IEC 61850-8-1,and IEC 61850-9-x.Finally this part explains how the interoperability is reached. NOTE Interchangeability requires that devices replacing other devices need to provide the very same functionality and communication as the devices to be replaced.IEC 61850 supports Interchangeability to some ex- tent.Interchangeability can be reached by additional specifications.The scope of IEC 61850 is limited to interoperability. This part of IEC 61850 is intended for all stakeholders of standardised communication and standardised systems in the utility industry.It provides an overview and introduction on the parts IEC61850-7-4,IEC61850-7-3,IEC61850-7-2,IEC61850-6,and IEC61850-8-1.
